Day of defeat high definition is a pack which includes :
- High definition player models
- HD weapon skins, with phong and specular maps
- Real sounds from WW2
- Detailed textures for the maps
- HD props and mapmodels (sandbags, hedgehogs)
- Graphics enhancer. Boosts dods graphical properties
Working on dods to be realistic.

I'm not sure if this still works, or ever did work, in DoD:S, but there used to be a command for TF2 called mat_picmip -10, this would leave the textures uncompressed (or compressed very little) and thus less blurry than the normal game. Sadly it was unceremoniously removed in the last major update for TF2. (Very High is mat_picmip -1)
